Hello to anyone that may give me some advice, I had a brand new 4.3 Mercruiser installed in my 2001 Chaparral 180 SSE in 2008, took it out once for about 5 hours and it has been sitting ever since. Well I am in the military and have deployed a few times since, well excuses, excuses I haven't done anything about it yet until now. What course of action should I do to get it started back up? tank has been about half full with premium gas the whole time. I have heard use, Sea Foam, Iso-Heet and fuel stabilizer. Should I drain the old gas first?

Looking for good advice without putting into the shop and getting charged alot.
Thank you

Def get that old gas out of there. Did you actually use a fuel stabilizer in the fuel before it sat for so long?

I'd take a sample of the gas, 'n give it the Smell Test,...
If it Smells like gasoline, it still is....
If it Don't smell like gasoline, pump it, 'n trash it...

if fuel dryed up in carb you may have to clean it
with carb cleaner and blow out with air.
fuel could dry and plug jets
